This technically isnt another stage kit thread

But is anybody running this?

Would it be safe? I think it would be safe, i mean the GM stage kit is a new tune, while these aftermarket companies are using piggybacks to run 2.8's.

You should try it and dyno it to see the a/f ratios.

this is definetly another stage kit thread. in all the others, people are talking about it, but nobody has done it yet.

I plan on running stage 2 with a 2.9 billetflow, then a 2.7 at the track. But not until i get my car fixed...

A 2.9" pully at 7000Rpm should give you less then 14,500Rpm at the suppercharger. Its red line is 16,000Rpm from what I have been able to find.
A 2.7" pully at 7000Rpm should give you BOUT 15,555Rpm at the supercharger.
Still below its redline.
THe thing we need to find out is how much it will afect the intake temps.
I see your bigest problem is going to be heat soke IMO.

Yeah, but im not going to bother with switching out the pulley from a 3" to a 2.9",if im gonna do it, im gonna do a 2.8.

i dont want to be the guinea pig, im just curious to see how it will do, and if other people had plans for this. It looks like it so,

2K5SS/SC?

I'll do it as soon as I get my damn kit in. I have the 2.8" on standby.

I am doing a 2.9 and a 2.7 on Stage one next week. I will let you know how it works out.

I am not worried about anything breaking on the car with this setup.

you can run a 2.9 stock....so a 2.7 or even a 2.6(thats what i'm doin) can be run with a stage kit.

people are runing 2.6 now...with maf-t and injecters.....our stage kit will allow us to do that as well

silverSS

the lowest you can go without machining the snout is 2.8 right? where are u getting the 2.7 and 2.6" pulley, thats crazy I would be scared to boost that much on this car

Id like to see how it would run with a 2.8 on a Stage Kit cobalt

I have Stage 2 and will be getting it installed on Thursday. Just bought a 2.8 ring from SFPH and I will see if it matches up with the GM hub.. I believe with the new flash on the computer that the car is not going to bleed the extra boost. Whatever boost it receives it will adjust from what i have read.

I believe the snout has to be machined when you go below 2.6. INTENSE has used a 2.5 and have verified gains from it.

Doc

I am also curious to see if the SFPH pullies will match the hub from GM.

silverSS

sweet, this is good news. I wouldnt even think twice about putting the 2,8 on with the GM Stage Kit, only problem is i would need a bigger tensioner

gotta pay to play! DAMITT

Supercharger limit is 14000 rpm. I found it on the eaton website for m62 but it is not there anymore.

I found the M-90 info on another site. its Max rpm is 14,000 rpm as well. see link
http://www.mn12performance.com/magnuson/magnuson.htm

also see news article. I think I may call them to see whats up. it appears they have taken over sales for auto S/C for Eaton and that is why the website change.

Now I did find that gm used a 73mm (2.874") pulley on the 300hp build up and did not say what REDLINE was intended to be.

Now I have a question. what is the crank dampener pulley circumference?

06black

the blower will use a 2.7 with no work to it...only a 2.6 and lower need the blower snout worked down a bit

JCswoosher2

sucks that billetflow only makes a 2.7 and a 2.9...... i want a 2.8. so ill go with intense 2.8 as daily driver and billetflow 2.7 for shows and track

astrocrep

I personally will probably go with a GM S2 and then if I want more power, slap a 2.8 on there.

most likley you're looking at the wrong generation blower we have a gen 5

1stbluSS

^^^^^ agreed..... you are looking at gen 4 numbers...

CobaltSS422

Correct



Well my order of my NGK BRK7E spark plus and 2.8 SFPH pulley shipped out today and will be here in 2-3 business days. I will update once I get it to let everyone know if it does or does not work with the GM hub

glockglade

i have a 2.8 from my old kit and my stage 1 from gm will be on by friday i will let you know how it goes..

The plugs do WONDERS with stage 2. The car runs much smoother now that i put the plugs in this afternoon. My friend got in the car today for the first time since the stage kit and plug install and noted like i did that the vibration from my transmission mount was reduced!!! And even before putting the plugs in i had reinstalled my weaopon-r damper and had noticed a slight vibe increase, so for him to say the vibes were less is a definate plus.

retrop

I'll be curious to see if the comp bleeds boost back to 12.5 with stage 1, cause stage 2 just builds and holds past 12.5 even without the bypass mod.

I am probly going to do this too, but I just wana know if this will put more stress on the engine and if it will waste a lot more gas cuz premium is expensive? And if you have any suggestions (Magnaflow vs Corsa?) for me, check out my signature and PM me.
